The study of biological materials and in particular of blood is a common procedure prescribed for diagnosis or in the processing process.
To avoid getting incorrect results, some rules must be followed before the tests.One of these concerns the use of tobacco products.
Is it possible to smoke before doing blood test?
For those who use tobacco products on a continuous basis, the question if you can smoke before the blood donation is very relevant.After all, it happens that a person and a couple of hours cannot spend without another snort.
Once in the body through the lungs, nicotine is almost immediately absorbed in the blood, significantly changing its structure.Furthermore, no matter which cigarettes were used by the smoker.Consequently, the analysis will show data that can be interpreted inadvertently by a doctor and can lead to incorrect diagnosis.
This state of affairs is full of useless care, which means prolonged disease and, in the worst case, developing complications.
Attention!Doctors prohibit smoking an hour before analysis and in some cases (which the specialist will warn in advance), there may be more abstinence.
As for the fact that it is possible to smoke after the blood donation, the restrictions are less severe, but they are still.Since immediately after blood fence, a person is weakened and the flow of nicotine will increase the load on the body, this can lead to unwanted consequences.Immediately after the blood donation, it is advisable to sit calmly for several minutes, then eat something, drink and only after remember the cigarettes.
Effect on blood indicators
An explanation of why it is impossible to smoke before giving blood is very simple: nicotine is able to influence most biomaterial indicators, in particular:
- change the properties of the platelets;
- significantly increase cholesterol;
- influence the relationship between hormones;
- change the hemoglobin indicators;
- increase the level of lymphocytes;
- Increases the content of catecholamines and cortisol.
Furthermore, a strong emission of catecholamine leads to spasm and, due to the difficulty of the bloodstream.Blood becomes more often, the biomaterial narrative process is complicated.
Nicotine negatively affects the process of providing internal oxygen.The hunger for oxygen that arose accordingly leads to a deterioration of well -being.
General blood test
Smoking affects an examination of general blood, following which it is possible to identify the development of inflammation or infection.As a result of the reaction between hemoglobin and carbon monoxide, in the high concentration of cigarette smoke, carroxiclobin form is formed.
This substance, unlike the protein, does not transport oxygen to tissues and organs.The hypoxia that rises causes excessive production of lymphocytes and their increase in blood content can be considered as the presence of an inflammatory process in the body.Therefore, the results of a general blood exam, donated shortly after smoking, will be incorrect.
Attention!The maximum concentration of nicotine in the blood is reached about half an hour after smoking, so before donating the blood from the finger, you should not smoke for at least 1-1.5 hours, but it is better to increase this period.
Biochemical analysis
A biochemical blood examination allows you to identify many internal pathologies, including the presence of cancer and diseases of the cardiovascular system.That's why it is so important to prepare for the study carefully, observing all the rules, including smoking before blood donation.
Venous blood is the most informative material, thanks to the study that you can have a fairly complete idea of the state of the body.But for this, the results of the analysis must correspond to the true state of affairs.
In the process of using the products of tobacco in the blood, not only the redistribution of certain substances.Smokers change the lipid-carbohydrate metabolism, which also affects blood indicators.Therefore, the specialists expressed a ban before leaving the blood from the vein categorically quite.Abstinence should be several hours.
Analysis for sugar
Sugar analysis helps to detect such a serious disease as diabetes.The answer to the question, you can smoke before giving blood for sugar, will also be negative.Scientists have shown that nicotine increases blood sugar.This fact, as well as a change in other indicators, can cause an incorrect interpretation of the results.
If the patient has an already increased level of sugar, even a smoked cigarette can significantly worsen the situation.
Blood on the HIV
When they donate blood to HIV infection, smoking is forbidden.It is necessary to abandon cigarettes 2-3 hours before the procedure.Nicotine and other substances contained in tobacco smoke inhibit the immune system.For this reason, the result of the HIV analysis can be inaccurate and not to view the patient's real conditions.
Search for hormones
The hormonal background is a very important indicator that affects the condition and performance of the entire body.Nicotine affects the adrenal glands, which leads to a greater synthesis of hormones, in particular cortisol.In addition, the man of smoke reduces the production of testosterone and in estrogen and prolactin women.
Before analyzing hormones, smoking can negatively affect the functioning of the thyroid gland.So it is desirable to abandon the cigarette a few hours before the blood jump.
How does the donation influence?
Nicotine causes a change in the structure of the blood at the cell level and also affects plasma.A person who has decided to give blood to help others undergo a mandatory examination.If the results are satisfactory, you can become a donor.
Since donated blood can be used in a wide variety of situations where the problems of life and death are sometimes solved, its quality should be perfect.Therefore, by instructing the future donor, the doctor speaks in detail of all the prohibitions and restrictions available.Including is announced in which time before the procedure it is necessary to refuse alcohol (2-3 days) and cigarettes (at least 1 hour).
In the blood of a passionate smoker, nicotine and other harmful substances received in the smoke process are constantly present, since a person smokes of such frequency that blood simply does not have time to clean.These people may not be authorized to be donated in the selection phase.
How to prepare a smoker for a blood test?
Before donating the blood for the analysis, you cannot only smoke.In order for the results of the study to be absolutely reliable and give a real idea of the patient's state of health, some preparation rules must be respected.They are as follows:
- The blood for the study is donated in the morning (from 8.00 to 11.00).This is due to the fact that the indicators go during the day and those obtained from the morning fence of biomaterial are used as average data.
- The blood is recommended to take an empty stomach and a break between the performance of the biomaterial and the last meal can be 8 to 14 hours.This object is due to the fact that the food that enters the body has an effect both on the condition of the blood and on the level of hormones.
- From smoking before analysis, you should also abstain.You can smoke a cigarette at least an hour before the blood donation.But for some studies, the withdrawal period increases.
- Strong emotional shocks and physical activity should be avoided, as they can influence biochemical indicators and hormonal levels.
- Make sure to warn the doctor for the drugs taken.Perhaps, for an analysis, they will have to refuse for a while.
You should know, not only as much as blood should not be smoked in front of the blood, but for what period it abstains from alcohol.For various studies, doctors call different terms, but the minimum - one day.
Urine habit and analysis
As for smoking before the urine analysis, the opinions of the doctors converge mainly.Most experts do not recommend using tobacco products before taking urine.This is due to the fact that the chemicals present in tobacco affect the composition of the urine and can distort the results obtained during the study.
Diffuits disagreements on which now it should pass after a smoked cigarette until the birth of the biological liquid.The main amount of nicotine and other harmful substances begins to be filtered by the kidneys and deposits in urine about 8 hours after entering the body.But tobacco almost immediately begins its effect on the body.
The ingredients of the tobacco, entering the body, influence the hormonal background, the liver and other internal organs.Therefore, it is advisable not to smoke at least an hour before the analysis, but it is better to refrain for 10-12 hours.
Conclusion
The data obtained following analysis can be incorrect due to a recently smoked cigarette.This will lead to an incorrect diagnosis and, consequently, an erroneously prescribed treatment.But given that regular smoke negatively affects the health and body conditions, the results of poor tests can reflect the real picture and indicate the available pathologies.
